Over a month after mating, Giant Pacific octopuses lay eggs. The species can lay 180,000 eggs in a single clutch, while Octopus rubescens clutches number up to 45,000 eggs and O. vulgaris clutches can number as much as 500,000 eggs. [78]: 75 Fertilised octopus eggs are layed as strings and within a shelter.
A female can lay up to 500 eggs; clusters of eggs are joined by special stalks. The female then sits with her eggs until they are ready to hatch. If any creature comes near the eggs, the female will attack it, though if it kills the creature, will not eat it. The eggs take 50 to 80 days to hatch, but will hatch more quickly in warmer waters.
Scavengers and other organisms often attempt to eat octopus eggs, even when the female is present to protect them. Giant Pacific octopus paralarvae are preyed upon by many other zooplankton and filter feeders. Marine mammals, such as harbor seals, sea otters, and sperm whales depend upon the giant Pacific octopus as a source of food.
Octopuses can survive outside the water for about 20-30 minutes, and some aren't making it back into the water in time. Skip to main content. Sign in. Mail. 24/7 Help. For premium support please ...
In the giant Pacific octopus, large eggs are laid in a den; it will often take several days to lay all of them. [112] Once the eggs are released and normally attached to a sheltered substrate, the female usually die shortly after, but octopuses and a few squids will look after their eggs afterwards.
Marine scientists discovered what they dubbed an 'octopus garden' nearly two miles below sea level. 'We were just absolutely floored.' Just off California, octopuses are converging by the thousands.
Researchers have documented an active octopus nursery, where hundreds of the deep-sea creatures cluster together to brood their eggs. Rare octopus discovery made 2 miles below the ocean surface ...
The eggs of Pinnoctopus cordifomis are of intermediate size (6.43 ± 0.21 mm L; 1.45 ± 0.11 mm W; 6.41 ± 0.52 mg TW) the yolk can be seen through the wall of the egg and represents approximately 57% of the eggs size, they are pear-shaped. Once the eggs are hatched paralarvae are released which survive without intervention for the duration of ...
